I am one of twenty struggling every day with multiple sclerosis to be included in an innovative, phase one stem cell clinical trial at the Tisch MS Research Center of New York. Now theres a mouthful. Please let me explain. Many of us read tidbits about cell therapy and think it simply is space-age medicine that will be launched in the future.

In fact, we are at the starting line now, and the race has begun. A phase one trial tests safety. The group is small, and all are treated with the real thing. No placebos, sugar pills. The trial tests autologous cells, which mean our own. That eliminates rejection and alters risk. No new medical procedure comes risk-free, but the dangers are minimal. The stem cells are pulled from bone marrow harvested from our breast bones. Sounds hideous. It is not.

In this trial, the stem cells are infused directly into the spinal column. Nope. Not painful at all. Then we watch and wait. Results, if there are to be any, can take many months to show themselves. This particular procedure has never been used before. I was the first in the group to be treated, making me the first in the world to have this done. For more than forty years, I have lived with an illness that left no room for hope. Suddenly, that has changed, though change does not necessarily come easily.

The expectation game is dangerous. No one really knows what to expect from this experiment. My doctor makes that point over and over. Yet it is hard to control the fantasies that inevitably pop into my head. The possibility of restoring at least some vision when I have been legally blind for years is enticing, to say the least. I used to run and race or simply hike up country hills. Now I hobble on a cane. I am lucky if I can stay on my feet walking two city blocks. The possibility of restored mobility takes my breath away.

I know better than to go too far down these roads in my mind, but that visual journey is unavoidable. Maybe that is okay. Hope is a funny thing. We need something to hope for. Any doctor will tell you attitude is an important factor in fighting a disease. I have learned the power of remaining positive. We need fuel to keep the engine running. Those flights of fancy, imagining we can be better than we are, to some extent can become self-fulfilling prophecies.

This is an exciting period in the history of medicine. That probably has been said throughout the ages. Science does not stand still. No one can see around the bend. That may be what makes hope possible, the idea that there is something just out of sight that is revolutionary and good, just waiting for us to get there.

The 2.4 million people suffering from multiple sclerosis worldwide have something to hope for with the discovery of a molecule which can be a key to creating a drug for the treatment of their ailment.

Dr. Ana Martinez, PhD, a research professor at the Spanish National Council for Research, revealed her patented molecular discovery during the launch of Ankar Pharma, the first Spanish-Filipino biotech company specializing in neurodegenerative diseases.

The revelation was made during a press conference held on Wednesday at the Zuellig Building in Makati where the management team showed up. The team is composed of Martinez, chief scientific officer; Dr. Carmen Gil, PhD, chief research officer; Jose Maria Olbes, vice president for business development; and Jose D. Leviste III, general counselor.

The company name was derived from the first names of the two female members of the management teamAna and Carmen, who was represented by Jose Leviste during the event.

Neurodegenerative diseases occur when the nervous system cells (neurons) in the brain and spinal cord begin to deteriorate. It is painful and heart-rending to see the health of a loved one who was once active deteriorate. Thats why the neurogenerative disease is a slow burn.

Multiple sclerosis is one of the worlds most common neurological disorders in many countries. It is the leading cause of nontraumatic disability in young adults.

Alzheimers and Parkinsons are the other neurodegenerative diseases. The number of people suffering from Alzheimers and Parkinsons diseases all over the world are 24 million and 7 million people, respectively.

With the help of investors from Spain and the Philippines, the biopharma company was created to develop a patented drug that promises to be a real game-changer.

Treatment for multiple sclerosis (MS) patients could be revolutionised in ground-breaking trials planned by a Cambridge scientist.

Dr Su Metcalfe, a University of Cambridge senior research associate based at Addenbrookes, has won a 150,000 award which will enable her team to proceed to pre-clinical trials in Nanotechnology.

The award is one of only five given out this year worldwide from major pharmaceutical company, Merck Serono, and the first to a UK scientist.

The technology developed for treatment of MS - an incurable autoimmune disease that attacks the central nervous system - by Dr Metcalfe uses tiny smart nanoparticles that act as magic bullets to deliver powerful factors known to increase repair of damaged myelin. The key factor is LIF, a stem cell protein.

The money from the Merck-Seronos Grants for Multiple Sclerosis International (GMSI) scheme will fund preclinical trials of Metcalfes nano-therapeutic device that taps into the bodys natural mechanisms for repair and avoids use of drugs.

Nanotechnology is now recognised as a key platform for healthcare, said Dr Metcalfe. Our smart technology allows us to target delivery of molecules able to repair myelin and also reduce inflammation.

By using a nanoparticle platform where the safety in humans is already confirmed, a hugely important feature for rapid progress towards the clinic, we can now expect to move to clinical trials within three to five years.

Multiple sclerosis commonly affects young adults and in the UK alone, more than 100,000 people have MS with 2,500 being diagnosed each year.

The disease causes damage to the nerve sheaths, or myelin, which normally insulate the electrical activity of nerve fibres in the brain and spinal cord.

Patients with Multiple Sclerosis (MS) were able to safely tolerate treatment with cells cultured from human placental tissue, according to a study published today in the journal Multiple Sclerosis and Related Disorders. The study, which is the first of its kind, was conducted by researchers at Mount Sinai, Celgene Cellular Therapeutics subsidiary of Celgene Corporation and collaborators at several other institutions.

While designed to determine safety of the treatment, early signals in the data also suggested that a preparation of cultured cells called PDA-001 may repair damaged nerve tissues in patients with MS. PDA-001 cells resemble mesenchymal, stromal stem cells found in many tissues of the body. Since the cells are expanded in cell cultures, one donor is able to supply enough cells for many patients.

This is the first time placenta-derived cells have been tested as a possible therapy for multiple sclerosis, said Fred Lublin, MD, Director of the Corinne Goldsmith Dickinson Center for Multiple Sclerosis, Professor of Neurology at Icahn School of Medicine at Mount Sinai and the lead investigator of the study. The next step will be to study larger numbers of MS patients to assess efficacy of the cells, but we could be looking at a new frontier in treatment for the disease.

MS is a chronic autoimmune disease in which the bodys immune system mounts recurring assaults on the myelin--the fatty, protective coating around nerve fibers in the central nervous system. This causes nerves to malfunction and can lead to paralysis and blindness. The disease usually begins as an episodic disorder called relapsing-remitting MS (RRMS), and for many sufferers, evolves into a chronic condition with worsening disability called secondary progressive MS (SPMS).

The new safety study was conducted on 16 MS patients (10 with RRMS and six with SPMS) between the ages of 18 and 65. Six patients were given a high dose of PDA-001, another six were given a lower dose, and four patients were given placebo. Any time the immune system is altered, say by an experimental treatment, there is always a risk for MS to worsen, noted Dr. Lublin. All subjects were given monthly brain scans over a six-month period to ensure they did not acquire any new or enlarging brain lesions, which would indicate a worsening of MS activity. No subjects showed any paradoxical worsening on MRI and after one year, the majority had stable or improved levels of disability.

Were hoping to learn more about how placental stromal cells contribute to myelin repair, said Dr. Lublin. We suspect they either convert to a myelin making cell, or they enhance the environment of the area where the damage is to allow for natural repair. Our long-term goal is to develop strategies to facilitate repair of the damaged nervous system.

Collaborators in the study included the Swedish Neuroscience Institute in Seattle, WA, MultiCare Health System-Neuroscience Center of Washington, London Health Sciences Centre at University Hospital in London, the Clinical Neuroscience Research Unit at the University of Minnesota, the University of Colorado Denver, The Ottawa Hospital Multiple Sclerosis Clinic, and the MS Comprehensive Care Center at SUNY.

Dr. Fred Lublin has received research support and financial compensation as an advisory board member from Celgene, the studys sponsor.

A vaccination against multiple sclerosis is in progress in the laboratory of SangKon Oh, PhD, at the Baylor Institute for Immunology Research. Along with Gerard Zurawski, PhD, and Ted Phillips, MD, Dr. Oh is applying new insights from research in dendritic cell vaccines to a multiple sclerosis vaccine.

Dr. Ohs approach is a very unique effort that would harness ones own immune system to suppress multiple sclerosis in an auto antigen-specific manner without disrupting other aspects of normal immunity, stated Dr. Phillips in a news release provided by Baylor Scott & White Health. The teams studies are unique in that they do not adversely affect the immune system like traditional multiple sclerosis treatment does. Instead, the immune system is preserved.

According to a video from Baylor Health Care System, dendritic cell vaccines are engineered by growing a patients blood-derived stem cells in vitro to become dendritic cells. These differentiated dendritic cells are then sensitized with immunogenic proteins. After, the dendritic cells are injected into the patient and, similar to a vaccine, prime lymphocytes to attack the immunogenic proteins within the body.

Current work was motivated by the application of dendritic cells to fighting cancer, but a unique property of the cells was discovered that allows their influence on immune function. We discovered that DC-ASGPR, one of the receptors expressed on human dendritic cells, has novel functions to promote antigen-specific regulatory T-cells that can efficiently suppress inflammatory responses, said Dr. Oh. This prompted us to test our discovery in autoimmune diseases where antigens are known.

From that time, the application of dendritic cell vaccines has grown extraordinarily. A phase 1 clinical trial may be in the works as soon as the year 2017. We need new treatments that, while highly efficacious, also minimally adversely impact the individuals immune system, said Dr. Phillips.

The findings from this research can be further applied to other diseases such as type 1 diabetes. For now, Dr. Oh is focused on their radical new approach to attack multiple sclerosis in its early stages before the immune system suffers damage.

Stem cells hold great promise as a means of repairing cells in conditions such as multiple sclerosis, stroke or injuries of the spinal cord because they have the ability to develop into almost any cell type. Now, new research shows that stem cell therapy can also work through a mechanism other than cell replacement.

In a study published today in Molecular Cell, a team of researchers led by the University of Cambridge has shown that stem cells "communicate" with cells by transferring molecules via fluid filled bags called vesicles, helping other cells to modify the damaging immune response around them.

Although scientists have speculated that stem cells might act rather like drugs in sensing signals, moving to specific areas of the body and executing complex reactions this is the first time that a molecular mechanism for this process has been demonstrated. By understanding this process better, researchers can identify ways of maximising the efficiency of stem-cell-based therapies.

Dr Stefano Pluchino from the Wellcome Trust-Medical Research Council Cambridge Stem Cell Institute, who led the study, said: "These tiny vesicles in stem cells contain molecules like proteins and nucleic acids that stimulate the target cells and help them to survive they act like mini "first aid kits".

"Essentially, they mirror how the stem cells respond to an inflammatory environment like that seen during complex neural injuries and diseases, and they pass this ability on to the target cells. We think this helps injured brain cells to repair themselves."

Mice with damage to brain cells such as the damage seen in multiple sclerosis show a remarkable level of recovery when neural stem/precursor cells (NPCs) are injected into their circulatory system. It has been suggested that this happens because the NPCs discharge molecules that regulate the immune system and that ultimately reduce tissue damage or enhance tissue repair.

The team of researchers from the UK, Australia, Italy, China and Spain has now shown that NPCs make vesicles when they are in the vicinity of an immune response, and especially in response to a small protein, or cytokine, called Interferon-gamma which is released by immune cells. This protein has the ability to regulate both the immune responses and intrinsic brain repair programmes and can alter the function of cells by regulating the activity of scores of genes.

(ANSA) - Boston, September 9 - Mesenchymal stem cell therapy to treat multiple sclerosis so far appears safe and without side effects, according to data released Tuesday and obtained through clinical trials on patients as part of the international Mesems project coordinated by University of Genoa neurologist Antonio Uccelli. The results were announced ahead of the World Congress on Treatment and Research in Multiple Sclerosis opening in Boston Wednesday through Saturday. The Mesems project involves researchers from nine countries - Italy, Spain, France, Britain, Sweden, Denmark, Switzerland, Canada and Australia. It is the first large phase II international multicentre clinical trial to determine the safety of a consensus treatment protocol established by the International Mesenchymal Stem Cells Transplantation Study Group to obtain information on its effectiveness on multiple sclerosis patients. So far, 81 patients have been involved in the project - half of the 160 needed for the whole clinical trial. About 73 - or 90% of those involved in blind testing - were given at least one injection with mesenchymal therapy or got a placebo while 51 - or 63% - were given both injections and 27 - 33% - completed the study. "The promising result is that so far none of these 27 people have suffered significant adverse events, which means that, so far, the treatment appears to be safe", said Uccelli. The neurologist warned that "caution is necessary" and that the effectiveness of the therapy can only be determined once the study is completed in 2016. Uccelli however added that preliminary studies on animals have persuaded researchers that mesenchymal stem cells "can halt inflammation on the central nervous system and probably succeed in protecting nervous tissue, even repairing it where damage is minor". Out of the 81 patients recruited so far, "28 are Italian and 10 of them have completed the study", Uccelli said, adding that all patients over the past year did relatively well except for one who was treated with placebo. The neurologist expressed the hope that "data in 2016 will give final confirmation that the therapy is effective so we can take the subsequent step with a larger phase III study aimed at demonstrating the role of stem cells as neurorepairers". Meanwhile Genoa's bioethics committee has approved a two-year extension of the project, which will be called Mesems Plus, "to verify, beyond the year of observation provided for by Mesems, the long-term safety of treatments in the study and the potential insurgence of adverse events in all those treated", said Uccelli.

Jeanne Loring and her Scripps Research Institute colleagues transplanted a set of cells into the spinal cords of mice that had lost use of their hind limbs to multiple sclerosis. As the experimentalists expected, within a week, the mice rejected the cells. But after another week, the mice began to walk.

We thought that they wouldnt do anything, says Loring, who directs theCenter for Regenerative Medicineat Scripps. But as her lab has since shown numerous times, and published in Stem Cell Reports, something that these particular so-called neural precursor cells dobeforethe immune system kicks them out seems to make the mouse better.

The cells Lorings team used are derived from induced pluripotent stem cells, which are mature cells, such as skin cells, that have been coaxed with a combination of chemicals to return to an earlier stage of development.

Induced pluripotent cells, also known as iPS cells, pose a number of opportunities for medicine. For instance, Loring is using iPS cells from Parkinsons disease and multiple sclerosis patients to reconstitute cell types that may be damaged in people with those conditions. She is also using them to test how certain drugs or treatments may affect damaged cells in people with conditions such as autism spectrum disorders.

Loring says no viable long-term treatments exist for the diseases her team has been working on, including Alzheimers disease, Parkinsons disease, and multiple sclerosis, Thats where the need is, she says.

The neural precursor cells that Loring has been using in the mice with MS are young cells that havent quite gotten to the point of being nerves yet. Only certain types of these cells have such a dramatic Lazarus-like effect on the affected mice, but Lorings team can readily identify them based on DNA analysis.

Even so, theyre not yet ready to treat human MS patients with the approach, she says. First, the researchers want to identify what the cells producea protein, perhaps, or a set of proteinsthat allows the mice to walk.

For other diseases, however, researchers are closer to being ready to transplant working versions of reprogrammed cells into sick people.

Scientists at The New York Stem Cell Foundation (NYSCF) Research Institute are one step closer to creating a viable cell replacement therapy for multiple sclerosis from a patient's own cells.

For the first time, NYSCF scientists generated induced pluripotent stem (iPS) cells lines from skin samples of patients with primary progressive multiple sclerosis and further, they developed an accelerated protocol to induce these stem cells into becoming oligodendrocytes, the myelin-forming cells of the central nervous system implicated in multiple sclerosis and many other diseases.

Existing protocols for producing oligodendrocytes had taken almost half a year to produce, limiting the ability of researchers to conduct their research. This study has cut that time approximately in half, making the ability to utilize these cells in research much more feasible.

Stem cell lines and oligodendrocytes allow researchers to "turn back the clock" and observe how multiple sclerosis develops and progresses, potentially revealing the onset of the disease at a cellular level long before any symptoms are displayed. The improved protocol for deriving oligodendrocyte cells will also provide a platform for disease modeling, drug screening, and for replacing the damaged cells in the brain with healthy cells generated using this method.

"We are so close to finding new treatments and even cures for MS. The enhanced ability to derive the cells implicated in the disease will undoubtedly accelerate research for MS and many other diseases," said Susan L. Solomon, NYSCF Chief Executive Officer.

"We believe that this protocol will help the MS field and the larger scientific community to better understand human oligodendrocyte biology and the process of myelination. This is the first step towards very exciting studies: the ability to generate human oligodendrocytes in large amounts will serve as an unprecedented tool for developing remyelinating strategies and the study of patient-specific cells may shed light on intrinsic pathogenic mechanisms that lead to progressive MS." said Dr. Valentina Fossati, NYSCF -- Helmsley Investigator and senior author on the paper.

In multiple sclerosis, the protective covering of axons, called myelin, becomes damaged and lost. In this study, the scientists not only improved the protocol for making the myelin-forming cells but they showed that the oligodendrocytes derived from the skin of primary progressive patients are functional, and therefore able to form their own myelin when put into a mouse model. This is an initial step towards developing future autologous cell transplantation therapies in multiple sclerosis patients

This important advance opens up critical new avenues of research to study multiple sclerosis and other diseases. Oligodendrocytes are implicated in many different disorders, therefore this research not only moves multiple sclerosis research forward, it allows NYSCF and other scientists the ability to study all demyelinating and central nervous system disorders.

"Oligodendrocytes are increasingly recognized as having an absolutely essential role in the function of the normal nervous system, as well as in the setting of neurodegenerative diseases,such as multiple sclerosis. The new work from the NYSCF Research Institute will help to improve our understanding of these important cells. In addition, being able to generate large numbers of patient-specific oligodendrocytes will support both cell transplantation therapeutics for demyelinating diseases and the identification of new classes of drugs to treat such disorders," said Dr. Lee Rubin, NYSCF Scientific Advisor and Director of Translational Medicine at the Harvard Stem Cell Institute.

Multiple sclerosis is a chronic, inflammatory, demyelinating disease of the central nervous system, distinguished by recurrent episodes of demyelination and the consequent neurological symptoms. Primary progressive multiple sclerosis is the most severe form of multiple sclerosis, characterized by a steady neurological decline from the onset of the disease. Currently, there are no effective treatments or cures for primary progressive multiple sclerosis and treatments relies merely on symptom management.

According to President George W. Bush, the stem cell research bill, which Bush vetoed on July 20, would "support the taking of innocent human life in the hope of finding medical benefits for others... it crosses a moral boundary that our decent society needs to respect."

Point taken. I just need to ask two questions. Why is "killing" stem cells, which have no proven brain function or EEG (electroencephalogram) pattern and nothing to "live" for, crossing a moral boundary? It seems to the president that it is not crossing a moral boundary to kill (no quotes, we're definitely killing in this case) innocent civilian Iraqis in the hope of benefiting the greater population of Iraq and the U.S.

According to leading scientists in the field, our society has defined death as the loss of the cerebral EEG pattern. Some scientists have also thought that the acquisition of the human EEG, which occurs at about 27 weeks of life, should be defined as when a human life begins. This view has been put forth most concretely by scientists Morowitz and Trefil (1992).

ABC Researcher Kaylene Younger is one of two inaugural recipients of the Metcalf Prize.

A Tasmanian researcher will use a $50,000 national prize for stem cell research which may help treat conditions like Alzheimer's disease and multiple sclerosis.

Dr Kaylene Young has won an inaugural Metcalf Prize from the National Stem Cell Foundation of Australia.

Her research has already uncovered that people have lazy or inactive brain cells and are common in people with multiple sclerosis, Alzheimer's and other degenerative diseases.

They are also found in people with a brain injury.

She has told ABC Local Radio her research will help improve the understanding of brain cell behaviour in order to treat disorders or damage.

She believes she can persuade cells to self repair and wake up, either by stimulation or electrically.

"[I'm] really trying to find what it is that controls their behaviours, what makes them divide, what makes them able to generate different types of brain cells in order to be able to use them for therapeutic treatments for things like Alzheimer's disease, multiple sclerosis and even brain cancers," Dr Young said.

"What I am really trying to do is push our endogenous stem cells, the stem cells that are already in our brain every day, to just work that little bit harder."

In this image, the top row shows the stem cells transplanted into the mouse spinal cord. The lower row shows a close-up of the stem cells (brown). By day 7 post-transplant, the stem cells are no longer detectable. Within this short period of time, the stem cells have sent chemical signals to the mouses own cells, enabling them to repair the nerve damage caused by MS. (image: Lu Chen)

For patients with multiple sclerosis (MS), current treatment options only address early-stage symptoms of the debilitating disease. Now, new research has found a potential treatment that could both stop disease progression and repair existing damage.

In a study published in Stem Cell Reports, researchers utilized a group of paralyzed mice genetically engineered to have an MS-like condition. Initially, the researchers set out to study the mechanisms of stem cell rejection in the mice. However, two weeks after injecting the mice with human neural stem cells, the researchers made the unexpected discovery that the mice had regained their ability to walk.

This had a lot of luck to do with it; right place, right time co-senior author Jeanne Loring, director of the Center for Regenerative Medicine at The Scripps Research Institute in La Jolla, California, told FoxNews.com. [co-senior author Tom Lane] called me up and said, Youre not going to believe this. He sent me a video, and it showed the mice running around the cages. I said, Are you sure these are the same mice?

Loring, whose lab specializes in turning human stem cells into neural precursor cells, or pluripotent cells, collaborated with Tom Lane, a professor of pathology at the University of Utah whose focus is on neuroinflammatory diseases of the central nervous system. The team was interested in stem cell rejection in MS models in order to understand the underlying molecular and cellular mechanisms contributing to rejection of potential stem cell therapies for the disease.

Multiple sclerosis is an autoimmune disease that affects more than 2.3 million people worldwide. For people with MS, the immune system misguidedly attacks the bodys myelin, the insulating coating on nerve fibers.

In a nutshell, its the rubber sheath that protects the electrical wire; the axon that extends from the nerves cell body is insulated by myelin, Lane, who began the study while at the University of California, Irvine, told FoxNews.com

Once the myelin has been lost, nerve fibers are unable to transmit electric signals efficiently, leading to symptoms such as vision and motor skill problems, fatigue, slurred speech, memory difficulties and depression.

The researchers inadvertent treatment appeared to work in two ways. First, there was a decrease of inflammation within the central nervous system of the mice, preventing the disease from progressing. Secondly, the injected cells released proteins that signaled cells to regenerate myelin and repair existing damage.

While the stem cells were rejected in the mice after 10 days, researchers were able to see improvements for up to six months after initial implantation.

Mice severely disabled by a multiple sclerosis (MS) -- like condition could walk less than two weeks following treatment with human stem cells. The finding, which uncovers new avenues for treating MS, will be published online on May 15, 2014, in the journal Stem Cell Reports.

When scientists transplanted human stem cells into MS mice, they predicted the cells would be rejected, much like rejection of an organ transplant.

Expecting no benefit to the mice, they were surprised when the experiment yielded spectacular results.

"My postdoctoral fellow Dr. Lu Chen came to me and said, 'The mice are walking.' I didn't believe her," said co-senior author, Tom Lane, Ph.D., a professor of pathology at the University of Utah, who began the work at University of California, Irvine.

Within just 10 to 14 days, the mice regained motor skills. Six months later, they still showed no signs of slowing down.

"This result opens up a whole new area of research for us," said co-senior author Jeanne Loring, Ph.D., co-senior author and professor at The Scripps Research Institute in La Jolla, Calif.

More than 2.3 million people worldwide have MS, a disease where the immune system attacks myelin, an insulation layer surrounding nerve fibers. The resulting damage inhibits nerve impulses, producing symptoms that include difficulty walking, impaired vision, fatigue and pain.

The MS mice treated with human stem cells experience a reversal of symptoms. Immune attacks are blunted, and damaged myelin is repaired, explaining their dramatic recovery. The discovery could help patients with latter, or progressive, stages of the disease, for whom there are no treatments.

Counterintuitively, the researchers' original prediction that the mice would reject the stem cells, came true. There are no signs of the cells after one week. In that short window, they send chemical signals that instruct the mouse's own cells to repair the damage caused by MS. This realization could be important for therapy development.

"Rather than having to engraft stem cells into a patient, which can be challenging, we might be able to put those chemical signals into a drug that can be used to deliver the therapy much more easily," said Lane.

THURSDAY, May 15, 2014 (HealthDay News) -- Mice disabled by a multiple sclerosis-like condition were able to walk again a few weeks after receiving human neural stem cell transplants, a new study shows.

While research in mice often fails to pan out in humans, the researchers believe the finding hints at new ways to treat people with MS.

The mice with the MS-like condition had to be fed by hand because they could not stand long enough to eat and drink on their own. But within 10 to 14 days of receiving the human neural stem cells, the rodents regained the ability to walk, along with other motor skills. This improvement was still evident six months later, the researchers said.

The study authors said they were surprised by the results of what they believed was to be a routine experiment. They had expected that the transplanted cells would be rejected by the mice.

"My postdoctoral fellow Dr. Lu Chen came to me and said, 'The mice are walking.' I didn't believe her," study co-senior author Tom Lane, a professor of pathology at the University of Utah, said in a university news release.

The study was published online May 15 in the journal Stem Cell Reports.

"This result opens up a whole new area of research for us to figure out why it worked," co-senior author Jeanne Loring, director of the Center for Regenerative Medicine at The Scripps Research Institute in La Jolla, Calif., said in the news release.

The next step on the road toward possible clinical trials in people is to assess the safety and durability of the stem cell therapy in mice.

Newswise LA JOLLA, CAMay 15, 2014Mice crippled by an autoimmune disease similar to multiple sclerosis (MS) regained the ability to walk and run after a team of researchers led by scientists at The Scripps Research Institute (TSRI), University of Utah and University of California (UC), Irvine implanted human stem cells into their injured spinal cords.

Remarkably, the mice recovered even after their bodies rejected the human stem cells. When we implanted the human cells into mice that were paralyzed, they got up and started walking a couple of weeks later, and they completely recovered over the next several months, said study co-leader Jeanne Loring, a professor of developmental neurobiology at TSRI.

Thomas Lane, an immunologist at the University of Utah who co-led the study with Loring, said he had never seen anything like it. Weve been studying mouse stem cells for a long time, but we never saw the clinical improvement that occurred with the human cells that Dr. Loring's lab provided, said Lane, who began the study at UC Irvine.

The mices dramatic recovery, which is reported online ahead of print by the journal Stem Cell Reports, could lead to new ways to treat multiple sclerosis in humans.

"This is a great step forward in the development of new therapies for stopping disease progression and promoting repair for MS patients, said co-author Craig Walsh, a UC Irvine immunologist.

Stem Cell Therapy for MS

MS is an autoimmune disease of the brain and spinal cord that affects more than a half-million people in North America and Europe, and more than two million worldwide. In MS, immune cells known as T cells invade the upper spinal cord and brain, causing inflammation and ultimately the loss of an insulating coating on nerve fibers called myelin. Affected nerve fibers lose their ability to transmit electrical signals efficiently, and this can eventually lead to symptoms such as limb weakness, numbness and tingling, fatigue, vision problems, slurred speech, memory difficulties and depression.

Current therapies, such as interferon beta, aim to suppress the immune attack that strips the myelin from nerve fibers. But they are only partially effective and often have significant adverse side effects. Lorings group at TSRI has been searching for another way to treat MS using human pluripotent stem cells, which are cells that have the potential to transform into any of the cell types in the body.

Newswise (SALT LAKE CITY) - Mice severely disabled by a multiple sclerosis (MS) like condition could walk less than two weeks following treatment with human stem cells. The finding, which uncovers new avenues for treating MS, will be published online on May 15, 2014, in the journal Stem Cell Reports.

Expecting no benefit to the mice, they were surprised when the experiment yielded spectacular results.

My postdoctoral fellow Dr. Lu Chen came to me and said, The mice are walking. I didnt believe her, said co-senior author, Tom Lane, Ph.D., a professor of pathology at the University of Utah, who began the work at University of California, Irvine.

Within just 10 to 14 days, the mice regained motor skills. Six months later, they still showed no signs of slowing down.

This result opens up a whole new area of research for us, said co-senior author Jeanne Loring, Ph.D., co-senior author and professor at The Scripps Research Institute in La Jolla, Calif.

More than 2.3 million people worldwide have MS, a disease where the immune system attacks myelin, an insulation layer surrounding nerve fibers. The resulting damage inhibits nerve impulses, producing symptoms that include difficulty walking, impaired vision, fatigue and pain.

The MS mice treated with human stem cells experience a reversal of symptoms. Immune attacks are blunted, and damaged myelin is repaired, explaining their dramatic recovery. The discovery could help patients with latter, or progressive, stages of the disease, for whom there are no treatments.

The Tisch MS Research Center of New York (Tisch MSRCNY) today announced that they surpassed their campaign goal on Indiegogo.com to raise funds for their FDA-Approved Phase I Clinical Stem Cell Trial. The funding will be directly applied to the study and stem cell research at Tisch MSRCNY.

The target of $300K was met and surpassed within the allotted four weeks of the campaign's launch raising a total amount of $317,540. We are overwhelmed and grateful for the generosity shown by our community of patients and friends, stated Dr. Saud A. Sadiq, Chief Research Scientist at Tisch MSRCNY and the studys principal investigator. He added, Funding is like oxygen for research. Without financial support, our research into regenerative therapy cannot survive.

As a non-profit,Tisch MS Research Center chose Indiegogo as a perfect platform since it has not received federal, state, or corporate funding to cover costs of this study. The crowd sourcing website heightened awareness and introduced new philanthropists to the Centers mission to repair the damage caused by multiple sclerosis.

The show of support has been tremendous, but our work is not done, said David Greenstein, Chairman of the Board of Directors at Tisch MSRCNY. We need the success of this campaign to jump start a steady stream of donations into the research center.

Thirteen thousand cyclists will ride to Austin this weekend after raising millions of dollars to fund research into Multiple Sclerosis. The effort is paying off. A decade ago, there was little hope for victims. Now drugs exist that reduce the severity and frequency of relapses, and slow the progression of the disease. The newest drug, Gilenya, is the first oral version of these medications. Several others are in the final stages of testing, and should be available in the next five years.

Genetic research has uncovered several genes that trigger MS. One is associated with low Vitamin D levels.

The disease affects myelin, a conductive sheath around nerve cells. Stem cell researchers are learning how to grow cells that produce myelin, hopefully to someday restore function to damaged nerves.

Thought for the day: Whether you do the research or raise funds as a rider, the outlook for MS is finally getting brighter.

Translational Biosciences, a subsidiary of Medistem Panama, has received the green light for a phase I/II clinical trial using human umbilical cord-derived mesenchymal stem cells (UC-MSC) for multiple sclerosis from the Comit Nacional de Biotica de la Investigacin (CNEI) Institutional Review Board (IRB) in Panama.

According to the US National Multiple Sclerosis Society, in Multiple Sclerosis (MS), an abnormal immune-mediated T cell response attacks the myelin coating around nerve fibers in the central nervous system, as well as the nerve fibers themselves. This causes nerve impulses to slow or even halt, thus producing symptoms of MS that include fatigue; bladder and bowel problems; vision problems; and difficulty walking. The Cleveland Clinic reports that MS affects more than 350,000 people in the United States and 2.5 million worldwide.

Mesenchymal stem cells harvested from donated human umbilical cords after normal, healthy births possess anti-inflammatory and immune modulatory properties that may relieve MS symptoms. Because these cells are immune privileged, the recipients immune system does not reject them. These properties make UC-MSC interesting candidates for the treatment of multiple sclerosis and other autoimmune disorders.

Each patient will receive seven intravenous injections of UC-MSC over the course of 10 days. They will be assessed at 3 months and 12 months primarily for safety and secondarily for indications of efficacy.

The stem cell technology being utilized in this trial was developed by Neil Riordan, PhD, founder of Medistem Panama. The stem cells will be harvested and processed at Medistem Panamas 8000 sq. ft. ISO-9001 certified laboratory in the prestigious City of Knowledge. They will be administered at the Stem Cell Institute in Panama City, Panama.

From his research laboratory in Dallas, Texas, Dr. Riordan commented, Umbilical cord tissue provides an abundant, non-controversial supply of immune modulating mesenchymal stem cells. Preclinical and clinical research has demonstrated the anti-inflammatory and immune modulating effects of these cells. We look forward to the safety and efficacy data that will be generated by this clinical trial; the first in the western hemisphere testing the effects of umbilical cord mesenchymal stem cells on patients with multiple sclerosis.

The Principle Investigator is Jorge Paz-Rodriguez, MD. Dr. Paz-Rodriguez also serves as the Medical Director at the Stem Cell Institute.

A new study describes the complexity of the new T cell repertoire following immune-depleting therapy to treat multiple sclerosis, improving our understanding of immune tolerance and clinical outcomes.

In the Immune Tolerance Network's (ITN) HALT-MS study, 24 patients with relapsing, remitting multiple sclerosis received high-dose immunosuppression followed by a transplant of their own stem cells, called an autologous stem cell transplant, to potentially reprogram the immune system so that it stops attacking the brain and spinal cord. Data published in the Journal of Clinical Investigation quantified and characterized T cell populations following this aggressive regimen to understand how the reconstituting immune system is related to patient outcomes.

Using this approach, alongside conventional flow cytometry, the investigators found that CD4+ and CD8+ lymphocytes exhibit different reconstitution patterns following transplantation. The scientists observed that the dominant CD8+ T cell clones present at baseline were expanded at 12 months post-transplant, suggesting these clones were not effectively eradicated during treatment. In contrast, the dominant CD4+ T cell clones present at baseline were undetectable at 12 months, and the reconstituted CD4+ T cell repertoire was predominantly composed of new clones.

The results also suggest the possibility that differences in repertoire diversity early in the reconstitution process might be associated with clinical outcomes. Nineteen patients who responded to treatment had a more diverse repertoire two months following transplant compared to four patients who did not respond. Despite the low number of non-responders, these comparisons approached statistical significance and point to the possibility that complexity in the T cell compartment may be important for establishing immune tolerance.

This is one of the first studies to quantitatively compare the baseline T cell repertoire with the reconstituted repertoire following autologous stem cell transplant, and provides a previously unseen in-depth analysis of how the immune system reconstitutes itself following immune-depleting therapy.
